Chemotherapy is a common treatment for cancer. It uses strong drugs to kill cancer cells. However, chemotherapy can have side effects. One such side effect is high blood sugar. This article will explain how chemotherapy can raise blood sugar levels.
Understanding Blood Sugar
Blood sugar is the sugar found in your blood. It gives your body energy. The body controls blood sugar levels using a hormone called insulin. When blood sugar is too high, it is called hyperglycemia. This can be dangerous if not managed properly.

How Does Chemotherapy Affect Blood Sugar?
Chemotherapy can raise blood sugar levels. Some chemotherapy drugs can directly affect how your body uses insulin. This can lead to insulin resistance. Insulin resistance means your body does not use insulin well. As a result, blood sugar levels can rise.
Common Chemotherapy Drugs
Some chemotherapy drugs are known to cause high blood sugar. Here are a few:
- Asparaginase
- Busulfan
These drugs can change how your body handles sugar. Always talk to your doctor about your treatment. They can help you understand the risks.
The Role of Steroids
Sometimes, chemotherapy is given with steroids. Steroids can also raise blood sugar levels. They can make insulin resistance worse. If you are taking steroids, watch your blood sugar closely.
Signs of High Blood Sugar
It is important to know the signs of high blood sugar. Here are some common symptoms:
- Increased thirst
- Frequent urination
- Fatigue
- Blurred vision
If you notice these signs, contact your doctor. They can help you manage your blood sugar levels.
